NOZZLE.

Application filed January 10, 1923. Serial No. 611,742.

To all whom it may concern: 7

Be it known that I, HOMER B. MARCH, a citizen of the United States,residing at Muskegon, in the county of Muskegon and State of Michigan,have invented new and useful Improvements in Nozzles, of which thefollowing is a specification.

The present inventionrelates to nozzles, particularly such as are.employed to vent water from the horizontally disposed water pipes of anirrigating or sprinkling system; and its object is to provide such anozzle having a deflector adapted to be bent into a set position todirect the water issuing from the nozzle in a desired direction; andfurther to provide an improved screen for such a nozzle whereby anysolid matter in suspension in the water may be prevented from stoppingor interfering with the flow of the water through the nozzle.

Ihis and any other objects hereinafter appearing are attained by, andthe invention finds preferable embodiment in, the structure hereinafterparticularly described in the body of this specification and illus:trated by the accompanying drawings, in which Figure 1 is a verticalcentral longitudinal sectional view of a portion'of an irrigating pipe,to which my improved nozzles are applied, one of which isshown incentrallongitudinal section taken on line 11 of Figure 2; V

Figure 2 is an under side view of the same, one of the nozzles beingshown in transverse section taken on line 22 of Figure 1, and the othernozzle being shown in transverse section taken on line 2 -2 of Figure 1;

Figure 3 is a side View (reduced in size) of said pipe illustratingnozzles whose deflectors are bent to various set positions; and

Figure 4 is a transverse sectional view of the pipe taken on line 44 ofFigure 3.

In the embodiment of 'my invention chosen for illustration by thedrawings and for detailed description in the body of this specification,a portion of a horizontally disposed pipe 1 through which water forirrigating or sprinkling passes. is shown, to which pipe are applied aplurality of my nozzles 52, spaced apart at desired intervals.

As thus illustrated, these nozzles are threaded into openings throughthe wall of the pipe. Each nozzle has a passage theresage is seatedthereinand, as shown, ex-

tends outwardly beyond the inner end 6 of the nozzle and into theinterior of the pipe 1, and may be secured in position by a small lumpof solder 7. It will be seen that by thus rolling the screen into theinvolute form shown the openings in one layer of the screen are disposedat varying distances from the openings in the adjacent layer or 7layers, so that a very perfect screening out of any solid mattersuspended in the water is efl ected, and such matter is prevented fromentering the vent 4 and thus stopping or interfering with the flow ofthe water I therethrough.

'Ihe nozzle is furnished with a deflector 8, integral therewith andextending outwardly from the body portion 9 of the noz- 'zle adjacentits vent 4. 'This defiectoror its restricted portion 10 adjacent thenozzles body portionis bendable so that the deflector may be bent into aset position as desired, in. order that the stream issuing from the ventmay be directed in a desired direction. As shown, the lateral surface 11of the deflector is cross-sectionally convex and longitudinally concave,so that the water issuing from the vent may be not only deflected by-theconcavity of the deflector into the desired direction, but also spreadlaterally by the deflectors convexity.

In Figure 3 positions of the deflectors bent into different setpositions is illustrated.

It will be readily understood that the screen may be removed from thenozzle and unrolled into flat form in which form it may be readilycleaned of clogging substances, and may then be again rolled intoinvoluted or other cross-sectionally curved form and inserted into thenozzle; and'that any bendable foraminous sheet, whether of mesh form ornot, and whether involuted or bent into other cross-sectionally curvedform, may be thus removed from the nozzle, fiattened out for cleaningand again bent into such curved form and reinserted into the nozzle.

I claim: 1. In a device of the character described: a pipe having anopening through its side;

a nozzle having a passage therethrough and seated in said openin astrainer formed from a toraininous sheet rolled into a substantiallycoinpact roll, its adjacent convolutions contacting each other, insertedinto the nozzles passage.

2. In a device 01' the character described: a pipe having an openingthrough its side; a nozzle having a passage therethrough and seated insaid openin 'g a strainer formed from a toraminous sheet rolled into asubstantially compact roll, its adjacent convolntions contacting eachother, inserted into the nozzles passage and axially extending into thepipe transversely thereof.

A liquid strainer formed from a toraininous sheet rolled into asubstantially compact roll, its adjacent convolutions eontacting eachother, and positioned axiallytransversely t0 the flow of liquid screenedthereby.

In testimony whereof I have hereunto setmy hand atGrand Rapids,Michigan, this 12th day of December, 1922.

HOMER B. MARCH.
